E308LT1-1
A flux cored stainless wire that brings wire feed deposition rates to 304 and 304L fabrication, with a slag that supports the puddle for vertical up work.
What the designation means
- E
- Electrode carrying the welding current.
- 308L
- An austenitic 19 chromium, 9 nickel deposit with controlled low carbon, matched to the common 18-8 base metals.
- T
- Tubular flux cored construction.
- 1
- The position digit, indicating all position capability rather than flat and horizontal only.
- -1
- The shielding designator, calling for carbon dioxide as the external shielding gas.
At a glance
| Process | FCAW |
|---|---|
| Family | Stainless steel |
| Positions | All positions |
| Polarity | DCEP |
| Shielding | 100 percent carbon dioxide, which is what the -1 shielding designator specifies |
| Minimum tensile strength | 75 ksi |
Typical uses
- Stainless tank, hopper, and vessel fabrication
- Heavy stainless plate groove welds where deposition rate matters
- Vertical up fillet welds on austenitic stainless structures
How it runs
- Much higher deposition rate than covered stainless electrodes
- Fast freezing slag that supports out of position beads
- Bright, smooth bead face with full slag coverage
- Slag must be removed completely between passes to avoid inclusions
Storage and handling
Stainless flux cored wire is moisture sensitive; keep spools sealed with desiccant and rebag or oven store any spool left on the machine.
